I've been researching Otto and Etymotic lately, and just recently pulled the trigger on the Otto NoizeBarriers which are nearly identical to the Etymotic GSP Elite. Just received them today and the "high" setting is what I'll be using for deer hunting, except when I am making a lot of noise myself walking (I have moderate-severe hearing loss). The sound on "high" is loud but clear and smooth, much less harsh/crashy/screeching than my custom profiled 8-band hearing aids (Resound/Jabra). Directionality is also really good, but probably not quite as good as my hearing aids (which is not surprising to me). On "low", the ambient sound is just like when I am not wearing my hearing aids...which is simply too low for hunting.
There is something I wasn't 100% sure about, but was confirmed by Etymotic CS: the GSP-15 is exactly the same in terms of performanc, but with disposable zinc air batteries instead of the rechargeables.
So, depending on one's use profile, perhaps the GSP-15 is the best option...same performance, but you don't have to worry about the Li: ion batteries biting the bullet on you, after warranty expiration.

Hi ********,
Thank you for reaching out! You are 100% understanding the differences between the two products. The circuitry is consistent in both products, but the differentiator is going to be the disposable versus the rechargeable battery option.
Thank you,

Hi,
Can you confirm that the electronics hardware and software for the GSP15 and the GSE are just about identical, offering approximately the same performance in terms of blast suppression, ambient sound hearing, and hearing enhancement?
Hence, the only significant differences are the outer housing/controls and the type of power source (disposable vs. rechargeable batteries).
Is this about right?
If this is NOT correct, and there are differences in performance between the two models, can you please elaborate?
Thank you!
Regards,
